San Rensho, thanks for the reassurance. I'll get off my ass and go buy some new ones.
I tried this home-made press, which didn't get the cotter out, but it did bend it. You might be able to use it to press the new cotter in.
Get a socket that just fits over threaded end of the cotter. Get a big c-clamp and use it between the rounded end of the cotter and the socket over the threaded end of the cotter.
